Application filed June 28, 1916. Serial No. 105,517.

9 bands of hats, to indicate the ownership of x fective machine for 'dicated, and is embodied in the improveowner on the sweat the article bybranding the initials of the band, the machine including a carrier adapted to be reciprocated: by an operator, and in the preferred form of the machine, a disk movable with the carrier andadapted to be rotated theron, said disk having branding dies on its periphery, and heating means on the carrier adapted to heat said branding dies so that when the carrier and disk are depressed against the work' to be branded, a branding die brought by the rotation of the disk into operative position will act on the work.

I The invention has for its object to provide a simple, conveniently operated and efthe general purpose inments which I will now proceed to describe and claim.

Of the accompanying drawings forming a part of this specification:

Figure 1 represents a front elevation of a branding machine embodying my invention; Fig. 2 represents a section on line 22 of Fig. 1;

Fig. 3 represen a rear elevation of the branding disk;

Fig. 4 represents same;

Fig. 5 represents a side view of a portion of the machine looking toward the slde'opposite that shown by Fig. 2; Fig. 6 represents a view similar to a portion of Fig. '1, parts being shown in section.

The same reference characters indicate the same or similar parts in all the views.

In Figs l to 6 of the drawings, 12 represents a supporting frame adapted to be attached to a bench or table and provided with an upper guide 13 and a lower guide 14, said guides being preferably in alinement with each other, and spaced apart, as indicated by Fig. 2.

Mounted to reciprocate in the space hean edge "view of the mally presses tween the said guides is a carrier, which, in the preferred embodiment of the invention here shown, comprises a body portion 15,

an upper ex-tenslon 16, a lower extension 17,

and an outwardly projecting arm 18 between said extensions.

The upper extension is preferably provided with teeth'19 constituting a rack, and the frame is provided with a rock-shaft 20 having gear teeth 21, constituting a pinion segment meshing with said rack. The shaft 20-may be rocked to alternately raise and depressthe carrier by means of a hand lever 22. A spring 23 in the lower guide 14: northe carrier upwardly, as indicated by Fig. 2. To the lower guide is fixed an impression bed 21, preferably provided with a facing 25 of'yielding or compressible material.

26 represents a disk of metal mounted to rotate on a bearing stud 27 forming a detachable part of the carrier and having a head 28 which confines the disk on the stud and permits the free-rotation of the disk, said stud being at right angles with the path of movement of the carrier;

The carrier is provided with an outwardly projecting flange 29 surrounding the stud 27 and arranged in a plane at right angles therewith. The disk 26 is provided with an annular recess 30, opening toward the flange 29 and separated from the periphery of the disk by a relatively thin heat-conducting flange 31.

The carrier is provided with heating means projecting into the recess 30 and preferably embodied in an annular electrical heating unit 32 attached, as indicated by Fig. 2, to the flange 29. The outer periphery of the heating unit is in close proximity to the inner side of the heat-conducting flange 31 and slightly spaced therefrom.

The periphe of the disk 26 is provided with brandlng ies33, preferably formed on a ring or band 34 surrounding the per1ph ery of'the disk, and attached thereto by suitable means, such as screws 35. Heat is radiated by the heat-conductin flange 31 the latter to the branding dies, therefore simultaneously heate and conducted by which are To revent or minimize loss of heat by heating unit against the the disk, said rim having an inwardly projecting annular flange 37, overlappin the marginal portion of the outer side 0 the disk. The rim 36, its flange 37 and carrier fiange 39 constitute a heat-retaining hood or casing, which ractically incloses the marginal portion of the disk and the branding dies thereon.

The lower portions of the carrier flange 29, the rim 36 and its flange 37 are truncated as shown at 40 (Fig. 1) to expose the branding dies 33 at the lower portion of the disk, said portion being so related to the impression bed 24 that when the carrier and disk are depressed'the lowest die on the disk will brand a sweat band 8 placed on the impression bed, said band being at-v tached to a hat h and temporarily turned outwardly therefrom.

To the outer side of the disk is attached a spider composed of an annular marginal portion 42, a hub portion 43, radial arms 44 connecting the portions 42 and 43, said arms being separated by air spaces so that the spider is air-cooled. 45 represents a disk-rotating knob or handle, preferably of wood or other material which is a non-conductor of heat. Said handle is in alinement with the stud 27 and coaxial with the disk, and is secured to the spider hub 43 by means of a bolt 47 engaged with the spider hub and having a knob-confining nut 48 engaged with the knob, as indicated by Figs. 1 and 2. The operator by rotating the handle 45 is enabled to bring any desired branding die into operative position, suitable means being provided for yieldingly confining the disk with any die in position to operate,"

said means being preferably embodied in. a spring-pressed detent 50' (Fig. 2) adapted to engage either of a series .of sockets 53 formed in the inner edge of the disk flange Fig. 3. Y

The hood flange 37 is provided with an indicating member 54 arranged to cooperate with either of a circular series of indicating members 55 on the annular marginal portion 42 of the spider, said indicating members informing the operator which branding die is in operative position.

It will be seen that the described machine is adapted to convenientlyv brand hat sweat bands and other like articles.

To enable the impressions made by the brandin dies to be uniformly spaced apart, I provi e the means next described.

To a suitable portion of the frame at one edge of the impression bed I secure by a screw or screws 57 (Fig. 5) a pair of spring jaws'58, between which a sweat band 8 may be yieldingly grasped, the object of said jaws being to prevent loose movement of the sweat band and permit it to bemoved by i The slide has a 'reduced portion 62 projecting from one-side of the impression bed and adapted to be grasped and moved by the operator.

. A portion of the outwardly turned sweat band projects over the extension 62, and said portion and extension may be-grasped between the operators thumb and forefinger and moved in the direction of the arrow (Fig. I) after a character has been impressed on the band. This movement, con- 1 tinued until the slide 60 is arrested by the compressed spring 61, shifts the sweat band to position to receive another impression at.

a predetermined distance from the first.

When the branding is completed the sweat band may be withdrawn edgewise from the jaws 58. When the slide is released it is retracted by the spring 61 until arrested on against one side of the impression bed.
